Greetings,
It is possible to follow the following procedure to prepare one liter of solution , then you can get 0.1L

This is the absolute easiest way to make a phosophate buffer. https://www.youtube.com/watch?v=e1O8c6DZCAs I have visited numerous sites and have not found it spelled out so clearly anyplace else!! Kudos to this guy!
You have to use the HH equation and have both mono and dibasic forms of sodium phosphate.

Dear John
To calculate the phosphate buffer you can use the following protocol by change simply K2HPO4 with Na2HPO4 in the indicated table int the below link.
Example :Preparation of 0.1M Phosphate sodium buffer at 25°C
61.5 mL of Na2HPO4 (1M)+ 1L H20..................PH=7
13.2 mL of Na2HPO4 (1M)+ 1L H20..................PH=6
ect..............
Please find this link the process to calculate phosphate buffer concentration according different pH at 25°C : http://www.unl.edu/cahoonla/phosphate%20buffer.pdf
Hoping it could be helpful

 Dear John,
I read both pdf files. They are alright as you mentioned.
However, the following link contains a program that can calculate the components for the preparation of any buffer which makes our life much easier:
